What is "pixelface"

Pixelface was a CBBC children's sitcom. The programme followed the adventures of a group of video game characters, previously seen in the Backstage Access sketches in the programme Sorry, I've Got No Head.

The characters include: Aethelwynne, a snobbish elf from the questing game 'Sword of the Ancients'; Rex Dynamo, an unknown marsupial whose game of the same name centres on the collection of apples; Claireparker, a zombie-battling waitress from the game 'Return to Zombie City'; Alexia, a lion-dodging Lara Croft parody from the game 'Legend Hunter'; Kiki Nova, an enthusiastic character from a dance game 'Groove Academy 2', which is often belittled by the other characters, and Sergeant Riley, an alien-shooting army sergeant from the game 'Sentient Force', often accompanied by his robot friend Romford.
